I do, and I don't doubt that Haze has Punto Rojo in it, just as I am certain Big Herb's tale is equal parts Haze history and legend. As so much of the Haze story is.
Two things tell me Herb has never seen a Haze plant and has never spent any time in the Santa Cruz area.
Cannabis varieties may have reddish stems, but none have red "sap". If Herb had spent any time around live cannabis rather than Washington Square Park dime bags he'd know how silly this claim is.
Huh? This is just magical thinking. How does falling on the ground improve a seed plant's performance?
Who the f**k says "the Cruz"? It's like whenever someone refers to San Francisco as "Frisco". Frisco is a town in Texas. No one in the SF Bay area uses "Frisco" let alone "the Cruz". Strictly tourist talk.
I think the truth is less magical and heroic than the Haze tales. In the late 60s and 70s, the wide-open Central and South American field-grown mj markets were starting to feel pressure from US authorities. Smugglers started re-thinking the risk-reward of smuggling vs. growing. Indoor growing wasn't even a thing yet, and seedbanks didn't really exist. So smuggler-turned-growers planted what they had, like a farmer planting last year's seed corn. Only, some of that seed corn was composed of the best Central and South American weed making it to the States at the time, Columbian Gold, Colombian Red (Punta Roja), Alcapulco Gold, etc.
As line growers do, they collected open-pollinated seed from the best plants each year for a few seasons. The best of these lines became Haze because the best pot dealers were always good marketers and Jimi Hendrix had put out a song called Purple Haze about the strongest, most psychedelic LSD around at the time, and calling their pot Haze was good marketing.
Sensimilla technique was just coming into the culture at the time, so it's no doubt that many Haze buds were sold with some seeds. Additionally, the typical higher frequency of intersexuality of sativa varieties no doubt helped ensure seeded bud was sold, and many different folks came to hold Haze seeds.
Even Herb admits the original breeders and the "Haze Brothers" who never called themselves that weren't really breeders at all, just traditional line farmers. So the strain was never stabilized, or even isolated, from the larger Central and South American landraces they originated from.
"Original" Haze is probably best described as a Central California coastal landrace sativa, more a family of related genotypes than a single strain. Which makes all the Holy Grail-chasing for the "original" a bit silly to me, like folks who pined for a Beatles reunion until there weren't enough Beatles left to fill a phone booth.
Haze to me is more genre than a strain, a collection of breeding values and traits that is focused on cross-breeding tropical mountain sativas, eschewing indica in order to preserve the clear, energetic high that these sativas are famous for. That brings many compromises, one being that the strains are not bred for indoor cultivation. One of the main focuses of my work is trying to acclimatize Haze hybrids to indoor environments without sacrificing the family's best traits.
